Ethics is concerned with the basis for moral judgments of “right” and “wrong” and is central to the clinical endeavor. Many clinicians integrate ethical estimations into their work without much conscious awareness. However, explicit use of ethical principles and frameworks can help navigate clinical decision-making when there is a sense of moral conflict or ambiguity about the “right” course of action. This article aims to highlight the key concepts and principles in clinical ethics as they apply to IECMH practice and stimulate a bigger conversation in the profession around how to support each other to maintain high ethical standards in working with young children and their families. Specifically, the authors consider the relevance of Beauchamp and Childress’ four principles framework (respect for autonomy, beneficence, non-maleficence, and justice), and address some of the special ethical challenges in the field, namely, the vulnerability of the infant, the need for a competent workforce, caring for caregivers, and the problem of multiple patients. Finally, the role of infant rights is briefly explored, noting the significant interest and debate that has been generated by the publication of the World Association of Infant Mental Health’s Position Paper on the Rights of Infants.
